hejjaya mele hhejjeyanikkuta –
There is a lot of Shastra in this : The literal translation is “Keeping one foot on another come forward” Or a more sane translation would appear to be “Come to me putting steps”
But why has Dasa Sreshsta Purandara Dasaru chosen this style of expression; no word of his is futile. To understand this, we need to understand the circumstance of composing the song.
Since Purandara Dasaru is an Aproksha Gynani, the Lord showed him visions of his leelas from time to time. SRI Purandara Dasaru would immidiately burst out with devotion and compose a song.
The vision for this song is, puttu Sri Krishna or a child Sri Krishna is running around the house. Her mother Yashoda is chasing him around. Yashoda has a special amsha of MahaLaxmi else no one can touch Sri Krishna. Dasaru sees this vision and he notices one thing.

Yashoda places her feet or hejje(footstep) only where Sri Krishna’s hejje (footprint) is present. Dasaru immediately connects it with Shastra that Sri Hari and Sri MahaLaxmi are nitya aviyogi, they don’t have even a moment of separation. Sri MahaLaxmi will come only where her husband Sri Hari is honoured and respected. Sri MahaLaxmi is the ultimate wife. She blesses and bestows grace to people only when they worship/respect her husband Sri Krishna.

To view this in another angle; Sri MahaLaxmi is the Abhimani Devata for all the shastras, Vedas, Puranas, Itihasa etc. (Vidya Laxmi). The entire Shastras follow the footsteps of Sri Krishna.

HARI SARVOTHAMMA !!!! VAYU JEEVOTHAMMA !!!!

Dasaru sees Sri Krishna running towards him and sees Sri MahaLaxmi in Yashoda running towards him and composes this song.

majjigeyoLagina beNNeyante – like butter appearing from buttermilk
* Buttermilk or Yogurt drink, is churned with a churning rod repeatedly to form butter.
#1) This reference is to the Samudhra Manthana (During KurmaAvatara the milk ocean was churned and Sri MahaLaxmi appeared in a special roopa and married Sri Vishnu)
Sri MahaLaxmi got must be married to Sri Hari or in other words, money/intellegence/education must be directed towards Sri Hari.

#2) This refers also to the Sadhane towards Sri Hari, Upanishads and Sri HariKathaAmruthSara talk about Sri Hari residing in arani(a type of sacred wood) sticks in the form of fire. Only when the arani sticks are rubbed together does the fire appear. Only when the buttermilk is churned that butter appears. Only when the Shastras are contemplated on deeply under the guidance of Tattvavada parampare does the true and real meaning come out.

attittalagalade bhaktara maneyali nitya mahOtsava nitya sumangaLa
Your devotees (Sri Hari and yours, Sri MahaLaxmi is never prayed alone; always with Sri Hari)
never face any trouble whatsoever; their houses are always happy; everyday is a festival and there is all around happiness and auspiciousness every day
